The repellents in the M-1960 clothing impregnant are 2-butyl- 2-ethyl-l, 3-propane dial, N-butylacetanilide, and benzyl benzoate. They can be analyzed quantitatively by gas chromatography on an 8-foot column of 5% Dow-Corning Silicone 550 on Haloport-F using a thermal conductivity detector. Analyses are conducted at 225 . on as little as 200 micrograms of each repellent, about 15 minutes being required for a single run. An internal standard is included to eliminate error, owing to sample injection.
